IMPROVEMENT lN FANNlNG-MILLS.

Specification forming part of Letters Patent No. 127,912, dated June 11, 1872.

To all whom it may concern:

Be it known that I, ABNER NIEBEL, of Tif fin, in the county of Seneca and in the State of Ohio, have invented certain new and useful Improvements in Fanning-Mills or Seed-Oleaners; and do hereby declare that the following is a full, clear, and exact description thereof, referencebein g had to the accompanying drawin g and to theletters of reference marked thereon making a part of this specification.

The nature of my invention consists in an improved arrangement of parts in a fanning-mill, as will be hereinafter more fully set forth.

In order to enable others skilled in the art to which my invention appertains to make and use the same, I will proceed to describe its construction and operation, referring to the annexed drawing, in which Figure 1 is a side elevation, Fig. 2 a longitudinal vertical section, and Fig. 3 a horizontal section, of a fanning-mill, showing my improvements.

I construct my mill in any of the known forms, except the shoe A, which I let pass clear through the mill and allow it to shake the whole length, and inclined downward from rear to front. At the rear end of the mill the shoe A is suspended by means of two springs, B B, attached to the sides of the shoe, and extending upward passing through the upper girth of the mill snugly, so as to hold them steady, and at the same time adjustable, so as to be raised or lowered. At the lower or front end of the shoe it is suspended by means of two straps, G G-one on each side-one end of each of said straps being attached to the body of the mill, and the other to the side of the shoe. At the lower end of the shoe are attached springs D D-one on each side-extending backward on the same incline with the shoe, and the upper ends of said springs attached to the main body of the mill. Inside of the mill, in rear of the fan E and just in front of the upper sieves, are blocksor triangular pieces G G, attached in a vertical position to the sides of the mill, which blocks or pieces fill up the vacant space between the sides of the mill and the shoe above the same,

thus directing the wind onto the sieves, and

preventing any waste of air between the sides of the mill and the shoe. In the shoe A is placed a screen, 11, which extends clear through almost the entire length of the shoe, giving a length of screen for the grain to pass over which enables the operator to more fully screen all the impurities out of the grain.

The object of the springs attached to the shoe is to steady the shoe and prevent it from wabbling, and to give it an even and perfect shake without tearing the same to pieces. A shoe suspended in this form cannot be used without these springs.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

The within-described fanningmill, consistin g of the exterior frame, the shoe A, springs 1 B and D, straps 0, fan E, triangular pieces Gr, and screen H, all of said parts being constructed and arranged as and for the purposes herein set forth. v

In testimony that I claim the foregoing I have hereunto set my hand this 11th day of December, 1871.
